The picture
Across 2,607 MOT tests, the Xjr returns 77.1% first-time pass — roughly in line with the UK fleet average. The single most-logged Major fail is a torn suspension dust cover. The strength or continuity of the load bearing and a number-plate lamp out round out the top three. Average tested mileage sits at 96,922, which is the lens to read those failure rankings through. If you own one and the next test is close, the ranked list below is a sensible pre-test checklist.

Year-band analysis
First-time MOT pass rate split by registration band. A 15.1-point gap between bands means the year you buy Jaguar Xjr has a real effect on what turns up at the garage.
Best band to buy
94.1%
2018–2020 registration
the 2018–2020 band climbs to 94.1% — a 15.1-point improvement. Tests in this band average 44,331 miles — roughly 54K miles fewer on the clock than the older band. Failures here are mostly wear items: damaged but not adversely affecting driver's view, not working — the structural issues that drag down older examples don't appear in the top-10 for this band. The stricter post-2018 MOT test rules meant manufacturers had to tighten up emissions and electrical checks, but this band still shows far fewer major failures on suspension and bodywork than the older fleet.
Band to be cautious about
79.0%
Pre-2018 registration
On the older band (pre-2018), the data shows a 79.0% pass rate against a fleet average of 94.1% on the newer band. The main culprits logged at test: ball joint dust cover severely deteriorated, inoperative in the case of multiple lamps…, and damaged but not adversely affecting driver's view. Average mileage on test for this band is 98,743 miles — high-mileage wear items are a recurring theme.
Best band to buy: 2018-2020 (94.1% first-time pass). Worst band to avoid: pre-2018 (79.0% pass). That's a 15.1-point spread across 5,372 older tests and 119 newer ones — year of build makes a material difference on this model.

Use the failure ranking as a pre-test checklist or a haggling lever. Treat the headline pass rate as a fleet-wide trend, not a guarantee on any individual car.
If you own a Xjr and your last MOT looked nothing like the ranked failures above, that's normal — individual cars vary widely. The ranking shows the patterns testers flag most often across the country.
